Their sons were Jon Havtoresson to Elingård and Sigurd Havtoresson to Sudreim.

Their daughter was Agnes Sigurdsdotter, who married the Swedish nobleman Jon Marteinsson (Stjerne) († ca. 1400) and who was the mother of Sigurd Jonsson (Stjerne) († 1453) to Sudreim, Giske, and Bjarkøy. Sigurd was Regent of Norway, and he was as a royal descendant offered the throne, but rejected these suggestions. His son Junker Hans Sigurdsson (Stjerne) († 1466) was the family's last man in Norway.
